Abstract
Hematuria is usually only noticed early in the case of macrohematuria. In around half of affected children, macrohematuria is caused by a urinary tract infection. In all other cases, a careful diagnosis is required. In addition to a detailed medical history, this builds upon a precise examination of the urine (microscopy, quantitative determination of proteinuria [mg albumin/g creatinine in spontaneously voided urine]) and measurement of blood pressure. The work-up usually includes sonography as the primary imaging modality. Invasive diagnostic tests using cystoscopy are only necessary in exceptional cases. If there is evidence of glomerulonephritis, a kidney biopsy may be indicated. Careful attention should be given to persisting microhematuria (> 6 months) and Alport syndrome should be confirmed or ruled out. Heterozygotic Alport syndrome can also be a possible cause of chronic renal failure.
